if desired, the blocks may be formed of glazed In Fig. 5 the body 24 ofthe block is given or unglazed clay. These blocks may be conasubstantially flat rectangular contour, is veniently formed in molds, asis usual in this provided with the alining groove 18, and car- 35 art,the faces of the mold being shaped to ries a plurality of projectingsupporting- 5 give the desired contour of the finished artishelves 8,these shelves having the pockets cle.

We do not,

therefore, desire to be limited to the details of the disclosure whichhas been made in this case; but

What We claim as new, and what we desire to secure by Letters Patent, isset forth in the appended claims:

1. The building-block having a body provided With an alining grooveextending around the same and provided with a plurality ofsupporting-shelves projecting from one face of said block, said shelveshaving an upturned outer edge and being reinforced-by a metallicreinforce embedded in said block, each of said shelves being providedwith ribs to form a plurality of supportinggrooves in its upper face.

2. The buildingblock formed of reinforced concrete comprising a bodyformed with an alining groove and with supportingshelves having pocketsformed integral with said block and extending outward from one face ofthe same.

3. The building block formed of reinforced concrete comprising a bodyprovided with supporting-shelves having pockets formed integral Withsaid body and extending outward from the face of the same. 7

4. The building block comprising a body, provided with supportingshelves having pockets formed integral with said body and extendingoutward from the face of the same.
